About This Quiz

Motherboards

In this chapter, you will learn how to

• Explain how motherboards work
• Identify the types of motherboards
• Explain chipset varieties
• Upgrade and install motherboards
• Troubleshoot motherboard problems

2. On Intel-based motherboards, which chip enables the CPU to interact with
RAM?

Memorybridge

Northbridge

Southbridge

Super I/O

The Northbridge enables the communication between the CPU and RAM.

Explanation

The Northbridge enables the communication between the CPU and RAM.

3. Solon has a very buggy computer that keeps locking up at odd moments
and rebooting spontaneously. He suspects the motherboard. How should
he test it?

Check settings and verify good components.

Verify good components and document all testing.

Replace the motherboard first to see if the problems disappear.

Check settings, verify good components, replace components, anddocument all testing.

Solon needs to check settings, verify good components, replace
components, and document all testing.

Explanation

Solon needs to check settings, verify good components, replace
components, and document all testing.

4. Martin bought a new motherboard to replace his older ATX motherboard. As
he left the shop, the tech on duty called after him, “Check your standouts!”
What could the tech have meant?

Standouts are the connectors on the motherboard for the front panelbuttons, like the on/off switch and reset button.

Standouts are the metal edges on some cases that aren’t rolled.

Standouts are the metal connectors that attach the motherboardto the case.

Standouts are the dongles that enable a motherboard to support morethan four USB ports.

Standouts are the metal connectors that attach the motherboard to the case.

Explanation

Standouts are the metal connectors that attach the motherboard to the case.

5. Brian bought a new motherboard that advertised support for eight USB ports.
When he pulled the motherboard out of the box, however, he found that it
only had four USB ports! What’s likely the issue here?

The extra four USB ports will connect to the front of the case or via adongle to an expansion slot.

The extra four USB ports require an add-on expansion card.

The FireWire port will have a splitter that makes it four USB ports.

The motherboard chipset might support eight USB ports, but themanufacturer only included four ports.

The extra four USB ports most likely connect to the front of the case or via
a dongle to an expansion slot.

Explanation

The extra four USB ports most likely connect to the front of the case or via
a dongle to an expansion slot.

6. Which of the following form factors offers the best cooling?

ATX

BTX

CTX

Although not widely adopted by the industry, BTX motherboards offer
superior cooling to AT or ATX systems.

Explanation

Although not widely adopted by the industry, BTX motherboards offer
superior cooling to AT or ATX systems.

7. Which of the following chips enables an Athlon 64 to use dual-channel
DDR RAM?

ATI 200 Express

NVIDIA nForce 570 SLI Intel

NVIDIA nForce 590 SLI AMD

None of the above

Athlon 64 CPUs have a memory controller built in; thus, none of the chips
listed handles memory access for the CPU.

Explanation

Athlon 64 CPUs have a memory controller built in; thus, none of the chips
listed handles memory access for the CPU.

8. Amanda bought a new system that, right in the middle of an important
presentation, gave her a blue screen of death. Now her system won’t boot at
all, not even to CMOS. After extensive troubleshooting, she determined that
the motherboard was at fault and replaced it. Now the system runs fine. What
was the most likely cause of the problem?

Burn-in failure

Electro-static discharge

Component failure

Power supply failure

Although all the answers are plausible, the best answer here is that her
system suffered burn-in failure.

Explanation

Although all the answers are plausible, the best answer here is that her
system suffered burn-in failure.

9. Steve has been tasked to upgrade ten systems at his office. The systems
currently have microATX motherboards with 512 MB of DDR RAM and
Athlon XP CPUs.

Primary objective: Upgrade ten systems.

Optional objectives: Use the current cases and use the current RAM.

Proposed solution: Purchase ten microATX motherboards with NVIDIA
nForce 570 SLI Intel chipsets and ten Pentium D CPUs.

The proposed solution:

Accomplishes only the primary objective.

Accomplishes the primary objective and one of the optional objectives.

Accomplishes the primary objective and both of the optional objectives.

Accomplishes neither the primary nor the optional objectives.

The motherboards would fit just fine in the cases because the switch
from AMD to Intel CPUs has nothing to do with the form factor of the
motherboards. Steve slipped up, however, because the chipset on the new
motherboards requires DDR2 rather than DDR RAM.

Explanation

10. On modern motherboards, which chip most commonly supports floppy
drives and infrared ports?

Memorybridge

Northbridge

Southbridge

Super I/O

The Super I/O chip handles older technologies such as floppy drives and
infrared ports.

Explanation

The Super I/O chip handles older technologies such as floppy drives and
infrared ports.
